TEREX SERVICE DEPARTMENT
PURPOSE:
To advise potentially hazardous condition.
DETAIL:
It has been brought to our attention that 'Viton' material used in manufacture of oil seals and 'O' rings, produces a
highly corrosive acid (Hydrofluoric) when subjected to temperatures above 315° C.
The resulting contamination can have extreme consequences on human tissue since it is almost impossible to
remove after contact.
We therefore recommend the following procedure when it is necessary to inspect any equipment that has been
subjected to a high temperature i.e. fire.
a. Visually inspect for any gaskets or seals which have suffered from heat; they will appear black and sticky.
b. If this is affirmed - Do Not Touch
c. Make enquiries to ascertain the material composition. Any Fluoro-elastomer (Viton, Fluorel or Tecmoflon)
should be considered dangerous but natural rubber and nitrile are non-hazardous.
d. If Fluoro-elastomer seals have been used, then the affected area MUST be decontaminated before
undertaking further work.
e. Disposable Heavy Duty Gloves (Neoprene) MUST be worn and the affected area decontaminated by washing
thoroughly with Limewater (Calcium Hydroxide solution).
f. Any cloths, residue and gloves used MUST be safely discarded after use.
Note: Burning of the discarded items is NOT RECOMMENDED, except in an approved incineration process
where the gaseous products are treated by alkaline scrubbing.

Proper service and repair is important to the safe, reliable operation of all motor vehicles. The service
procedures recommended and described in this publication, are effective methods for performing service
operations. Some of these service operations require the use of tools specially designed for the purpose.
The special tools should be used when, and as recommended.
It is important to note that this publication contains various WARNINGS and NOTES which should be
carefully read in order to minimize the risk of personal injury to personnel, or the possibility that improper
service methods will be followed which may damage the vehicle or render it unsafe. It is also important to
understand these WARNINGS and NOTES are not exhaustive. It is not possible to know, evaluate andadvise the service trade of ALL conceivable ways in which service might be carried out, or, of the
possible hazardous consequences of each way. Consequently, no such broad evaluation has been
undertaken. Accordingly, anyone who uses a service procedure, or tool, which is not recommended, must
first satisfy themselves thoroughly that neither their safety, nor vehicle safety, will be jeopardized by the
service method he/she selects.
Two types of heading are used in this manual to attract your attention.
1. WARNING - This symbol is used when an operating procedure, practice, etc., which, if not correctly
followed could result in personal injury or loss of life. Look for this symbol to point out important safety
precautions. It means - ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
2. Note - This is used when an operating procedure, practice, etc., which, if not strictly observed, could result in
damage to or destruction of equipment.
IMPORTANT SAFETY NOTICE
WARNING
Never use parts which are altered, modified, or weakened in operation. This can seriously
jeopardize the integrity of the machine and could result in property damage or serious personal
injury.

Welding
WARNINGS
Before any welding is done on a machineequipped with any electronic systems,disconnect the following (if applicable) in thisorder: Battery earth cable, battery supplycable, alternator earth cables, alternator supplycables and electrical connections at the engineECM, transmission ECU, body control lever,hydraulics ECU and cab bulkhead to avoiddamage to electrical components. Turn offbattery master switch to isolate the batteriesbefore disconnecting any components.After welding connect all of the above in the
reverse order.
Before any welding is done ensure all paint hasbeen removed from the area to be welded.Failure to do so may result in hazardous fumesbeing given off from the paint.
Note: Always fasten the welding machines groundcable to the piece/frame being welded if possible.
Electric arc welding is recommended for all weldedframe repairs. Since the nature and extent of damageto the frame cannot be predetermined, no definiterepair procedure can be established. As a general rulehowever, if parts are twisted, bent or pulled apart, or aframe is bent or out of alignment, no welding should bedone until the parts are straightened or realigned.
Successfully welded repairs will depend to a greatextent upon the use of the proper equipment, materialsand the ability of the welder. The Customer SupportDepartment can be consulted regarding the feasibility
of welding repairs.
WARNING
Welding and flame cutting cadmium platedmetals produce odourless fumes which are
toxic. Recommended industrial hygienepractice for protection of the welding operatorfrom the cadmium fumes and metallic oxidesrequires enclosure ventilation specificallydesigned for the welding process. Arespiratory protective device such as theM.S.A. 'Gasfoe' respirator with G.M.A. cartridgewill provide protection against cadmium,fumes and metallic oxides. The 'Gasfoe'respirator has been approved by the U.S.Bureau of Mines: Approval number 23B-10,and is designed to protect against gases,
vapours, and/or metal fumes.
Note: The current from the welding rod always followsthe path of least resistance. If, for example, the groundclamp is attached to the rear frame when welding isperformed on the front frame, the current must pass aframe connection to return to the welding machine.Since the pivot coupling offers the least resistance butnot a sound electrical connection, small electric arcsmay be set up across the moving parts which maycause welding blotches on their wearing surfaces andincrease the wear rate of these components.
General Welding Procedure
The following general procedure should be used forthe repair of defects outwith the vicinity of alloy steelcastings.
1. Completely ARC-AIR gouge or grind out the crackuntil sound metal is reached. If ARC-AIR method isemployed, pre-heat area to 100° C (212° F), measure3 - 4" either side of repair prior to gouging. Oncompletion of gouging grind to remove thin carbonlayer.
2. Apply dye-penetrant check to ensure crack hasbeen completely removed.

CHASSIS - Frames
DESCRIPTION
The front and rear frames are all-welded high grade
steel fabrications, with rectangular box section beams
forming the main side and cross-members. These
heavy duty structures are designed to withstand the
severe loadings incurred when operating over roughterrain.
The front frame houses engine, transmission,
hydraulic and fuel tanks and carries the cab, front
suspension and front drive axle. The rear frame
carries the body, body cylinders, rear suspension
system and the rear drive axles.
Inter-frame oscillation is provided by a robust
cylindrical coupling, carried on large nylon bushes.
Steering is by frame articulation to 45 degrees either
side by two widely spaced vertical pivot pins in taper
roller bearings.
Note: For details on the articulation and oscillation
pivot and procedures for separating the front and rear
frames, refer to Section 100-0020, ARTICULATION
AND OSCILLATION PIVOT.
MAINTENANCE
Note: This section covers maintenance of the front
and rear frames only.
Inspection
Inspect the frames and attached parts at intervals not
exceeding 250 hours for cracked or broken welds and
bending of the frame. Any defects found should be
repaired before they progress into major failures.

Chassis - FramesSection 100-0010
Straightening
If the frame is not too badly sprung or twisted,
hydraulic straightening and aligning equipment can be
used to straighten the frame without dismantling the
machine. However, if the frame is severely damaged,it will be necessary to disassemble the machine in
order to repair or replace the frame assembly.
All straightening operations should be performed
without application of heat if possible. If heat must be
applied, do not heat the metal beyond a dull cherry red
colour, as it will result in serious weakening of the
frame by decreasing the tensile strength of the steel.
When it is necessary to apply heat, apply it uniformly
over the area to be straightened until the metal
reaches a uniform colour. Protect the heated surface
from drafts to prevent sudden cooling of the metal. If
the frame or frame parts cannot be straightened theymust be replaced.
Welding
WARNINGS
Before any welding is done on a machine
equipped with the DDEC system, disconnect
wiring harnesses at the ECM, connections at
body hydraulics joystick, all battery
connections at both positive and negativeterminals and ground cable to alternator to
avoid damage to electrical components. Turn
battery master switch to the 'Off' position
before disconnecting any components.
Remove battery ground cable first, and
reconnect last, to avoid damaging electrical
components.
Before any welding is done ensure all paint
has been removed from the area to be welded.
Failure to do so may result in hazardous fumes
being given off from the paint.
Note: Prior to welding, switch off/disconnect the
following in the order given. Failure to do so may
seriously damage the machines electrical
components.

After welding, connect all of the above in the reverse
order.
Note: Always fasten the welding machines ground
cable to the piece/frame being welded if possible.
Electric arc welding is recommended for all weldedframe repairs. Since the nature and extent of damage
to the frame cannot be predetermined, no definite
repair procedure can be established. As a general rule
however, if parts are twisted, bent or pulled apart, or a
frame is bent or out of alignment, no welding should be
done until the parts are straightened or realigned.
Successfully welded repairs will depend to a great
extent upon the use of the proper equipment, materials
and the ability of the welder. The Service Department
can be consulted regarding the feasibility of welding
repairs.
Reinforcement
Frame reinforcement can be made with channel, angle
or flat structural stock. Whenever possible, the
reinforcement should extend well beyond the bent,
broken or cracked area. The reinforcement stock
thickness should not exceed that of the frame stock
and the material should be of the same tensile
strength.
PaintingTo keep rust and corrosion to a minimum, periodic
painting of abrasions and other exposed metal areas
on the frames is highly recommended.
If painting of a frame is required, thoroughly clean the
areas to be painted. Apply a primer coat of synthetic
red oxide and then a finish coat of synthetic enamel.

DESCRIPTION AND OPERATION
The articulation and oscillation pivot allows the front
and rear frames to rotate horizontally (articulation)
and tilt laterally (oscillation) with respect to each
other. It is also the main load bearing coupling
between the two frames. The pivot assembly houses
the driveshaft connecting the drive between the front
and rear frames.
Articulation bearings, oscillation bushes, pivot
driveshaft bearing and associated parts can be
removed, inspected and replaced or renewed byfollowing the procedures outlined in this section.

DESCRIPTION
Numbers in parentheses refer to Fig. 1.
For engine make, model and specification, refer toSection 000-0000, GENERAL INFORMATION. Forengine servicing and repair data refer to the enginemanufacturers service manual.
The engine is mounted to the tractor frame at threepoints by a mounting bracket at the front of engine (1)and two rear mounts (18 & 19). Rubber isolationmounts (28) through engine mounts provide sufficientflexibility to absorb varying engine vibration and
torsional loads.
There are two full-flow oil filters (2) mounted on the
right hand side of engine (1) in a downward position.The filters are of the throw away, spin-on type. Oilsupplied by the engine oil pump passes through oilfilters (2) before reaching the various moving parts ofengine (1). The oil is forced by pump pressure througha passage in the filter adaptor and into the elements.Impurities are filtered out as the oil passes through theelements and out through another passage in the filteradaptor.
Engine coolant filter (3) and conditioner is a compactbypass type unit with a replaceable spin-on type
element mounted on the gear case cover at the frontright hand side of engine (1). Refer to Section

There are two spin-on type fuel filters mounted on theleft hand side of engine (1). Primary fuel filter (4) is inthe fuel flow and acts as a strainer and secondary fuel
filter (5) filters the fuel after having passed throughprimary fuel filter (4). The word 'Primary' or 'Secondaryis cast into the top of the respective adaptor to preventmismatching.

CONTROL (DDEC)
Description
Refer to Fig. 2.
WARNING
Before any welding is done on a machineequipped with the DDEC system, disconnectthe following in this order:Battery earth cable, battery supply cable,alternator earth cables, alternator supplycables, body hydraulics joystick, transmission(Est-37) connector, ECM interface harnessconnector (30 pin RHS), ECM sensor harnessconnector (30 pin LHS) and ECM engine totransmission datalink connector (6 pin RHS).Turn off battery master switch beforedisconnecting any components.
After welding connect all of the above in thereverse order.
The engine is equipped with DDEC which controls thetiming and amount of fuel injection by the electronicunit injectors (EUI). The system also monitorsseveral engine functions using electrical sensorswhich send electrical signals to the electronic controlmodule (ECM). The ECM then computes theincoming data and determines the correct fuel output
and timing for optimum power, fuel economy andemis
